Title: Simplex transmitter and receiver
Inventor: HITAI TAKASHI
IPC: H04B1/44
Filed: 1983-04-07
Abstract: PURPOSE:To reduce the loss of a transmit signal in transmission and to improve the efficiency of the whole transmitter and receiver by performing on-off control over a switching circuit and leading the transmit signal outputted from a transmission part to an antenna without passing it through a diode. CONSTITUTION:When an on-off switch 34 is opened during transmission, the transmit signal outputted from the transmission part 1 is led in the antenna 7 through an impedance matching circuit 4. This signal, on the other hand, is rectified on half-wave basis by a diode 31 because the on-off switch 34 is open, and when a coupling capacitor is charged to the crest value of the transmit signal, no current flows through the diode 31. Therefore, no transmit signal flows through the diode 31 after the completion of the charging of the coupling capacitor 32, so the transmit signal has no loss originating from this diode 31. On the other hand, when the on-off switch 34 is closed during reception, a receive signal from the antenna 7 is led to the input terminal 11 of a reception part 10 through the impedance matching circuit 34, diode 31, and coupling capacitor 32.

Afterwards, a suspending structure is loosened, axial force borne by the column 1 is transmitted to the base isolation device, a useless suspending structure is diverted to realize base isolation of the other column 2, and hereafter, the base isolation device is arranged in a similar procedure. Thus, base isolation realizing work is executed in a short construction period to reduce the construction cost.

Filed: 1989-03-14
Abstract: PURPOSE:To emit a stable liquid droplet between nozzles by providing a porous member composed of a polymer material of a hydrophobic-hydrophilic copolymer to the inner wall of a common ink sump on the side of an ink supply passage. CONSTITUTION:The pressure wave generated in a pressure chamber 2 propagates in the direction of an ink emitting orifice 1 as ink emitting energy and also propagates in the direction of an ink sump 5 through an ink supply passage 3. However, since the pressure wave propagating in the direction of the ink sump 5 is absorbed and attenuated by the porous member 4 provided to the inner wall of the ink sump 5 on the side of the ink supply passage 3, said pressure wave does not propagate to the ink sump 5 and does not also again propagate to the pressure chamber 2. Herein, the porous member 4 is constituted of a polymer material composed of a hydrophobic-hydrophilic copolymer and the polymer material is composed of a acrylonitrile/vinyl alcohol copolymer, an ethylene/vinyl alcohol copolymer or a vinyl chloride/vinyl alcohol copolymer.
